$6.05 because 10.09 × 0.6 is 6.054, round down because the last number is less than 5, and you have 6.05.

Joey is measuring the amount of time it takes for a frisbee to fly through the air he uses a stopwatch to time it and find that

marissa [1.9K]

Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%

Step-by-step explanation:

Step 1

Time as recorded by the stopwatch = 4.82 seconds

Real Time it takes for a Frisbee to fly through the air =5.05 seconds

percent error = Measured value – True Value /True value x 100.

= 4.82 - 5.05 / 5.05 x 100

=-0.23/5.05

=-0.0455 x 100

=4.5544%

Rounding to nearest 10th of a percent = - 4.6%

Answer:

Approximately, 159 men weighs more than 165 pounds and 159 men weighs less than 135 pounds.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 150 pounds

Standard Deviation, σ = 15

We are given that the distribution of weights of 1000 men is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P( men weighing more than 165 pounds)

P(x > 165)

$P( x > 165) = P( z > \displaystyle\frac{165 - 150}{15}) = P(z > 1)$

$= 1 - P(z \leq 1)$

Calculation the value from standard normal z table, we have,

$P(x > 165) = 1 - 0.8413 = 0.1587 = 15.87\%$

Approximately, 159 men weighs more than 165 pounds.

P(men weighing less than 135 pounds)

P(x < 135)

$P( x < 135) = P( z < \displaystyle\frac{135 - 150}{15}) = P(z < -1)$

Calculation the value from standard normal z table, we have,

$P(x < 135) = 0.1587 = 15.87\%$

Approximately, 159 men weighs less than 135 pounds.

Mary deposits $550 in a savings account at 3% simple annual interest. The

kupik [55]

Answer:

Domain: $t \geq 0$

Range: $v \geq 550$

Step-by-step explanation:

Given

$v = 550 + 16.5t$

Required

Determine the domain and the range

Solving for domain:

From the question, we understand that t represent years.

Because years can't be negative;

Then, we can conclude that the domain, t is:

$t \geq 0$

Solving for Range:

We solved domain to be $t \geq 0$

This implies that the minimum value of t is $t = 0$ and the maximum is infinity

Substitute 0 for t in $v = 550 + 16.5t$

$v = 550 + 16.5(0)$

$v = 550 + 0$

$v = 550$

Hence;

The range is $v \geq 550$
